JOHN HENRY HOLMES, OF NEWQASTLE-UPON-TYNE; ENGLAND.

APPARATUS FOR DISPENSING LIQUIDS. I

To all whom it may concern Be it known that I, J OHN HENRY HoIiMES;

a subject of the King of Great Britain and Ireland, residing at Portland Road, Newcastle-upon-Tyne, England, have invented a new and useful Improvement in Appa-' ratus for. DispensingLiquids, of which the following is a. specification.

This invention relates t improved apparatus for dispensing liq ids such for example as liquid soap in small quantities at a time, such quantities being of approximately equal volume and has for its object the provision of means for 'efl'ecting this purpose of a simple and inexpensive character adapted to insure certainty of action.

My invention consists in improvements in that class of apparatus in which, acontainer, a measuringchamber external thereto, a valve for controlling the passage of liquid from the container to the chamber,

and'another valve controlling the passage from the said ,chamber to the delivery, are so arranged that automatic operation is effected upon manual alteration of the capacity of the said measuring chamber; and

provides for the association of the container with the measuring chamber in fixed relation with each other and further in the arrangement of parts whereby the deliveryis effected by a single movement of the hand the refilling of the measuring chamber being effected automatically. In the case of liquid soap for example a small quantity is required to be delivered into thepalm of 'the' hand, and the apparatus herein described is specially suitable for use in this connection, although it is obvious it maybe used for other materials such for. example as scent or oil.

In order that better understood I will now proceed to by whichthe liquid to be dispensed is stored in a container a and is drawn off from the.

external measuring chamber a disposed below the said container (1. The liquid is normally retained in the container in spite of Specification of Letters Patent. 7

there. being a hole I) for the egress of the liquid by means of a valve 6 opening outv ward which closes said hole I). The valve 6 1s. pressed upward upon a seat 0 by a spring "d so as tokeep the valve. closed so long as the" apparatus is not being used for the extraction of the liquid. The seat 0 of this valve is adapted so that it maybe pushed upward by the hand of the operator pressing .upon a suitable-projection 6 carried by the seat 0 and this action causes the valve b to open and the-liquid to beejected on to the palm of the hand. To'enable the seat a of the valve to be pushed upward as described, it may be: carried in the center of a flexible diaphragm f rigidly supported at the edge, the natural elasticity of which causes-it to bulge downward but it can be pushed in the opposite direction by pressure exerted by the-hand of the o erator.-

This is the arrangement shown in F1g. far as it is at present described.

As an alternative to this arrangement the valve seat o as shown in Fig. 2 may be formed in a movable piston c in a small l so open ended cylinder is attached to the container a such piston being pressedldownward against a stop 14 by a spring Z but the piston can be pushed upward by the hand of the operator. I

To provide'for the opening'of the valve 72*- when the seat 0 is pushed upward and to insure the volume of the liquid ejected at each operation being approximately 0on stant, the following additional" mechamsm 1s embodied-in the apparatus. In Fig. 1 at a little distance above the flexible diaphragm f is arranged a rigid diaphragm g forminga false bottom to the container a and havin in its center a hole 71. adapted to be closed by a valve k.

I arrange the valves 72. and b to be me chanically operated as follows :-The lower valve 6 opens downward, and is pressed upward and normally held in the closed position bythe spring (l. The valve 6 has a stem m reaching upward and on this stem'm is carried the valve In which closes the hole [2. in the fixed diaphragm g'or the upper end of the cylinder 70. In the normal positionof the parts, this valve h is open and is disposed a little distance from its seat so that the liquid from the container a above .n'rayflow through. When the operator exerts sufficient upward pressure upon I the lower valve seat c he raises it together with its valve '5 valve stem m and upper valve it carried thereon,.until theupper valve it closes and prevents-further valvemotioni' A continued upward movement of the hand results in the opening of thelower'valve b a diminution in volume of the space a} and I m je tion or the liquid." 011 the return stroke by springpressurethe lower valve first closes immediately followed by the opening of the to valved thus allowing the How of liquid i=om-the cone.- tainer a -to take the place otzthat displacedtrom the space a. lltwill 'he' understood that the amount of liquid ejectedat one such .reduction may be varied'by alteringstrolre depends upon the reduction of vol-- ume lot-the space between the valves b. and

h after the upper; valve hhas closed and the length oi -stroke.

llt is obvious that the device may be adapted for use with a-b'ottle so that by in-' verting the bottle the extraction function can h e-carried out by. hand pressure on the device.

- Havingthus fully described my inven tion,-ll claim as new and desire to secure by Letters Patent:

1. An apparatus for dispensing liquids comprising in combination, a container, a deliveryyvalve seat rigidly mounted on the bottom of said container, a valve h adapted to open by a downward movement, a closed chamber of variable capacity rigidly. a't tached to and below said container for re ceiving liquid from the said delivery valve 72 externally operated means for varying' the capacity of said closedchamber, an'outlet valve :5 orrsaid closed chambermechanically connected with said' delivei vvalve to prevent' a continuous 'fiow -ofliquid from said chamber; a movableseatfor said outlet valve mounted on the saidf'mea ns fee.

memes varyingthe capacity of the said closed chamber to forcibly eject the liquid from the saidpliamber, means for applying hand pressure to the said movable valve seat to cause thediscnargeiof liquid past the same from the said chamber to the exterior of the bottom of said container, a valve k adapted to open byn downwardmovement, a closed chaimiber of variable -capacity" rigidly at tached to and below "saidcontainer for-receiving liquid from the said delivery" valve k, externally operated means for varying" the capacity'of said closed-chamber;

outlet valve 6 onsaid closed chamberme chanically connected with said delivery valve to prevent a continuous flow of liquid from said chamber; a movable seat for said outlet 'valxe mounted on the saidmeans for varying-the capacity of the said closed chamber to allow the-ejection of the liquid -from thesa-id' chamber, means for applying hand pressure to the said movable valve seat to cause the discharge ot'liquidpast the same from the said chamber to theexterior of the apparatus, and yielding means associated with said valves,;f0r counteracting stantial-ly as described.
